Intermittent hypoxia (IH) is a direct consequence of obstructive sleep apnea syndrome (OSAS), which results in left ventricular dysfunction , remodeling and myocardial cell injury .Understanding the mechanisms of OSAS is important for us to prevent and treat the cardiovascular complications in the clinical practices .We summarize the effects of IH on left ventricular function , and analyze the mechanisms at the cellular and molecular levels , including oxidative stress, ion exchangers and inflammation .In addition, the effects of endothelin-1 and hypercapnia on IH-induced cardiac injury are discussed .

Objective To explore the clinical value of lymphocyte sub-population and NK levels in patients with primary lung malignant tumor and patients with chronic obstructive pulmonary disease (COPD). Methods The percentage of CD3 +,CD4 +, CD8 +, CD19 + and NK cells were measured in 60 COPD patients and 50 primary lung malignant tumor patients and 40 normal control subjects using alkaline phosphatase antialkaline phosphatase (APAAP) assay, and CD4 +/CD8 + ratio was calculated. Results The levels of CD3 +,CD4 +,CD4 +/CD8 + and CD19 + cells were significantly lower in the patients with primary lung malignant tumor or COPD than those in the normal control subjects, which CD8 level was significantly higher (P0.05). No difference in the levels of CD3 +, CD4 + and CD8 + cells was found between the primary lung malignant tumor and COPD patients, but NK and CD19 + cells levels had significant difference(P

0.05).The stimulative index(SI)tested by MTT in MLR at stimulator-to-reactor cell ratio 1∶1,1∶10,1∶20,1∶40 and 1∶80 was 2.7,4.1,3.1,2.5 and 1.6,respectively.The proliferation of T cells stimulated by DCs could be detected at all stimulator-to-reactor ratio.Conclusion DCs could be successfully induced from peripheral blood monocyte in the patients with colorectal cancer by AIM-V serum-free media or by traditional FBS-contained media.AIM-V is more suitable for clinical immunotherapy because it can avoid the risk of allergic reaction for clinical purpose.AIM-V might take the place of serum-contained media to culture DCs.According to the results of MLR,DCs could stimulate allogenetic T cells proliferation at all stimulator-to-effector ratio,furthmore the optimal ratio is 1∶10 .

Objective To investigate the therapeutic effects of citalopram on alleviating painful symptoms in type 2 diabetes mellitus(DM) patients with complication of painful peripheral neuropathy.Methods Thirty-eight type 2 DM patients with painful peripheral neuropathy were randomly divided into control group(eighteen patients) and treatment group(twenty patients).The diabetes control(including fasting blood glucose) and general health state(including body mass index,liver function,renal function) of patients were recorded.Patients in control group were given conventional drugs(including hypoglycemic drugs,anodyne,neurotrophy drugs,antiplatelet drugs),and those in treatment group received conventional drugs plus antidepressant drugs(citalopram,20mg,q.i.d.for 14 days).Hamilton Depression Rating Scale for Depression(HAMD-17) was used to assess the depressive symptoms,and numeric pain intensity scale(NPIS) was used to assess the pain intensity on baseline and the 1st,7th and 14th day.At the same time,the levels of analgesic agents were recorded.Results On the 7th and 14th day,the HAMD-17 scores in treatment group(22.14?8.92,18.69?9.4) were significantly lowered compared with that in control group(26.81?9.79,25.71?9.92),P

An adult patient with hypophosphatasia caused by compound heterozygous mutations in alkaline phosphatase,liver /bone /kidney(ALPL)gene was investigated through comprehensively reviewing the medical history and clinical records of the proband and her family members in order to better understand the disease.The proband and her older sister had mild decreased serum alkaline phosphatase level accompanied with frequently nontraumatic fractures at limbs and all the teeth fell off at the age of 20 and 7, respectively.Both of them carried a missense mutation c.407G>A(p.Arg136His)in exon 5 and a deletion mutation c.1318_1320delAAC(p.Asn440del)in exon 12 simultaneously.Other four family members were p.Arg136His mutation carriers and two members were p.Asn440del mutation carriers.We found that p.Asn440del mutation was associated with the oral disorders.In this family, compound heterozygous manifested more serious symptoms, while heterozygous showed relatively mild symptoms.In addition, it is necessary to differentiate it from primary osteoporosis and other diseases of disturbed bone mineralization.

Objective:To evaluate arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors in the treatment of tibial eminence fracture.Methods:The 23 patients were retrospectively analyzed who had been treated at Department of Orthopedics, Beiing Shunyi District Hospital for tibial eminence fractures by arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors from October 2015 to December 2019. They were 15 males and 8 females, aged from 12 to 55 years (average, 35.5 years). All the injuries were unilateral (14 right and 9 left sides). According to the modified Meyers-McKeever classification, 2 cases belonged to type Ⅱ, 18 cases to type Ⅲ and 3 cases to type Ⅳ. Range of motion of the knee, Lysholm and International Knee Documentation Committee (IKDC) scores were observed before surgery, 1 month and 12 months after surgery. The anterior tibial slope angle (ATSA) on CT was measured preoperatively and 1 month after surgery for evaluation of fracture reduction.Results:All the 23 patients were followed up for an average of 23 months (from 12 to 52 months). Postoperatively, limited knee movement was observed in 2 patients and non-anatomic reduction in one patient. At 1 month and 12 months after operation, the Lysholm scores (61.4 ± 3.5 and 90.4 ± 4.3) and IKDC scores (69.6 ± 4.2 and 88.5 ± 3.0) were significantly improved compared with the preoperative values (45.4 ± 6.8 and 49.6 ± 3.9, respectively) ( P<0.05). ATSA was significantly restored from preoperative 4.2° ± 5.7° to -11.7° ± 2.9° at 1 month after operation ( P<0.05). Conclusion:In the treatment of tibial eminence fracture, arthroscopy-assisted tibial bone tunnel fixation combined with double-row anchors can achieve anatomical reduction and firm fixation, leading to satisfactory surgical outcomes.

Objective:This work aims to explore the long-term efficacy and complications of late-course accelerated hyperfrac-tionation (LCAHF) for treating nasopharyngeal carcinoma. Methods:A total of 58 patients who consulted from December 2005 to May 2008 and histologically proven nasopharyngeal carcinoma at initial diagnosis were randomized into an LCAHF group (experimental group) and a conventional fractionation (CF) group (control group). The treatment dose for both groups was 2 Gy per fraction once dai-ly, 5 days a week. After the 40 Gy to 50 Gy dose, the dosage in the LCAHF group was increased to two daily doses at 1.5 Gy per frac-tion 6 h apart, 5 days a week. The total dose in this group was 73 Gy to 76 Gy, the total dose in the CF group was 70 Gy to 76 Gy, with the total course of the treatment shortened by 0.5 weeks to 1.5 weeks in the former group. Results:The 5-year control rates of the naso-pharyngeal cancers was 86% in the LCAHF group and 59% in the CF group (P=0.021), with statistically significant differences be-tween the two groups. The late complications slightly increased in the LCAHF group than in the CF group, but the differences were not statistically significant. Conclusion:LCAHF treatment improves the local control of nasopharyngeal carcinoma without increasing the incidence of long-term complications.

Objective To explore the relative importance of factors of sleep quality in predicting the anxiety and depression emotion. Methods Sleep quality and emotional condition of 112 patients with coronary heart disease were investigated with Pittsburgh sleep quality index(PSQI), self-rating anxiety scale (SAS)and self-rating depression scale (SDS). The relation between sleep quality and emotional condition was analyzed deeply by dominance regression analysis. Results After controlling the demographic vari-able of the sex,factors of the sleep quality such as sleep efficiency and function in the daytime had predict-ing effect on depression emotion;factors such as function in the daytime, sleep quality, sleep efficiency and sleep time possessed predicting effect on anxiety emotion. Conclusions According to different contribu-tion of various factors of sleep quality to anxiety and depression emotion, we should implement selective medical and nursing intervention during clinical work.
